The mean scores for perceived benefits showed a greater increase in the casegroup than in the control group immediately after and six months after the intervention. Ebadi Fard Azar et al.21 showed that the construct of perceived benefits of physical activity in the intervention group significantly increased after training, but this was not true for the control group. This is consistent with the findings of the present study. In the study by Mehrab Beik et al. on the prevention of osteoporosis among women with low socioeconomic status, perceived benefits showed a significant increase after the intervention22. The increase in the perceived benefits can be the result of an emphasis in training on walking and diet, physical and psychological benefits of walking and the role of nutrition in preventing osteoporosis.
